Linda Evans was my best friend –like the sister I never had ,We did everything together: piano lessons ,movies, swimming , horseback riding.

When I was 13, my family moved away . Linda and I kept in touch through letters ,and we saw each other on special times — like my wedding and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often .One day a card that I sent came back , stamped “Address Unknown”. I had no idea about how to find Linda.

Over the years, I missed Linda very much. I wanted to share happiness of my children and then grandchildren . And I needed to share my sadness when my brother and then mother died, There was an empty place in my heart that only a friend like Linda could fill.

One day, I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman —Linda’s married name.“There must be thousands of Wagmans.”I thought, but I still wrote to her.

She called as soon as she got my letter, “Mrs , Tobin!”she said excitedly, “Linda Ev-ans Wagman is my mother.”

Minutes later I heard a voice that I recognized at once, even after 40 years . We laughed and cried and caught up on each other’s lives. Now the empty place in my heart is filled. And there’s one thing that Linda and I know for sure; We won’t lose each other again!
